Filed: 1984-03-26
Abstract: PURPOSE:To control combustion amount by means of specified air-fuel ratio through an inexpensive constitution, by a method wherein the control current of a proportional control valve located in a fuel feed passage is controlled in a staged manner by means of a value about coinciding with properties of the proportional valve depending on positive and negative of inclination of a current, and simultaneously, the switching terminal for the capacity of a blower is properly selected in response to control.

When a double electromagnetic valve 10 opened, a blower 4, simultaneously, is operated, ignition is made by means of an igniter 5, and hot air is discharged in a chamber. As a result of an indoor temperature being increased, an indoor temperature T detected by a thermistor 11 is increased, and when a difference DELTAT between the detected temperature and a set temperature To is reduced to not more than a given value, a control circuit 13 determines a control current I-1 to a proportional control valve 9, a blast amount Q-1 of the blower 4 is shifted from H to MH, and a combustion quantity is reduced as an air-fuel ratio is maintained about at a specified value. As noted above, a fuel amount and an air amount are controlled in a staged manner to hysteresis properties of the proportional control valve 9, and this enables varying of a combustion amount by means of a specified air-fuel ratio through an inexpensive constitution.
